Efficiently sharing user selected information with a set of determined recipients

ABSTRACT

Targeted information to be shared according to a “pre-analyzed user behavior” of a set of potential candidates is analyzed. The pre-analyzed user behavior is determined from a set of previously conveyed messages from a sender to one of the potential candidates. A list representing a determined subset of the potential candidates and related preference tools/applications is presented to the sender via a user interface. Tools/applications are determined for sending said targeted information content. An action message is sent to the tools/applications of selected candidates, which results in each of the subset of potential candidates receiving the targeted information.

BACKGROUND

The present invention relates to a method and system for efficientlysharing information via messaging applications.

Communication tools have become indispensable for the work and socialinteractions. Example communication tools can include an instant messagesystem, an e-mail system, a short message system, a network voicecommunication system, video conferences, a micro-blogging servicesystem, and the like. People use one or more of these systems/tools fordispatching information to friends, family members, and/or colleagues.

Given a wide variety of voluminous information (related to news,entertainment, medicine, or foods) and the groups or communities tocontact, it is often necessary to dispatch different information tospecific parties promptly. It may be difficult to identify a recipientto whom the information has to be rapidly dispatched and to determine anappropriate tool for dispatching the information. Further, a dispatchaddress (e.g., email address, phone number, IP address, etc.) often hasto be looked-up, which may require searching of multiple differentcontact repositories.

DETAILED DESCRIPTION

Once a user browses a webpage and finds useful information or aninteresting essay and wants to share it with friends/candidatesconcerned by means of an existing information sharing system (such as aninstant message system, or an e-mail system), then the user can take thefollowing steps.

-   -   1. specifying and reproducing useful or interesting information        content from an information source;    -   2. opening a contact list in an instant message or in an e-mail        system, and finding the communities and names of        candidates/persons who share the same habit or are interested in        the information;    -   3. determining a preferred tool for sending the information to        parties concerned/candidates so as to ensure that the parties        concerned are most likely to receive the information timely; and    -   4. sending the information to different parties        concerned/candidates by different preferred tools.

The whole process of sending the information has to be performedmanually and in a time-consuming manner. Usually, the information is nolonger real-time information at the moment when users are reading theinformation. It is because, after finding the information, the userstake time to share the information there between. To use differenttools/applications, the users have to perform a plurality of steps inorder to finalize the delivery of the information. At times, the usersmight not be sure whether a certain person is interested in theinformation, and thus the users are likely to omit some persons or sendthe information to wrong persons. Furthermore, the best friends of yoursmay lose the opportunity to receive, or may be denied the benefit fromreceiving, an instant message, such as breaking news, sales promotion,or limited free tickets, just because of a several minutes' delay causedby you, or because you simply forget to notify them.

Therefore, it may be imperative to eliminate the aforesaid drawbacks ofthe prior art by providing a solution of efficiently sharing informationby dispatching information to appropriate parties concerned/candidateswithout specifying potential parties concerned/candidates. Theseproblems were recognized and resolved during the course of developingthe disclosure.

Thus, embodiments of the present invention provide a solution ofefficiently sharing information by dispatching information toappropriate parties concerned/candidates without specifying potentialparties concerned/candidates. All the users need to do is to select theinformation which the users want to share with each other and theninform the system entailed by the present invention of the informationthus selected.

FIG. 1 is a schematic view of the structure of a system 100 forefficiently sharing information according to a specific embodiment ofthe present invention, such that FIG. 1 enables persons skilled in theart to gain insight into the present invention rather than restricts thescope of the present invention. In an exemplary embodiment, the system100 includes a server 110, one or more client-end computers 120, 130,140, 150 (such as a personal computer, a notebook computer, or a mobileelectronic device). The server 110 includes an information center and auser behavior database. Hence, the server is hereinafter known as aninformation center server. The information center includes an analyzingengine (module), a dispatching engine (module), and a synchronizingengine (module). The analyzing engine, the dispatching engine, and thesynchronizing engine are described in detail below. The client-endcomputers 120, 130, 140, 150 are connected to the information centerserver 110 via a network (not shown).

According to an embodiment of the present invention, the client-endcomputers are electronic products for executing applications to providean instant message, an e-mail, or a short message, or electronicproducts for executing other applications to dispatch information, suchas desktop computers, notebook computers, terminal apparatuses, mobilephones, or personal digital assistants. The client-end computers canalso execute applications like word processing services or browsers.

In one embodiment, the client-end computer is a general desktop computerincluding: a processor for executing various applications; a storingdevice for storing various information and program codes; a displaydevice; a communication and output/input device for use as an interfacefor communication with the users; and peripheral elements or otherelements with specific purposes. In other embodiments, the presentinvention may also be implemented in other manners and thus require moreother devices/elements or less other devices/elements.

In one embodiment, the information center server 110 can come in theform of a general computer, a computer with a special purpose, ahigh-level workstation, or a large host computer as needed, withoutaffecting the implementation of the present invention. The requirednetwork can also come in a connection of any type, including a wide areanetwork (WAN) or a local area network (LAN) with static IP, or atemporary connection to the Internet through an Internet serviceprovider (ISP), whether by cable connection or by wireless connection.The network can also have other hardware and software elements (such asan additional computer system, a router, or a firewall) not shown in theaccompanying drawings.

Each of the client-end computers for executing various applications(such as an instant message system, an e-mail system, or a short messagesystem) for dispatching information includes an information plug-in andthus can interact with the information center at the information centerserver 110. The information center server 110 is present in somecontemplated embodiments and absent in others. Information can beefficiently shared among the client-end computers, provided that each ofthe client-end computers includes a user behavior database and theinformation center built in the information center server 110.

It should be noted that many of the functional units described in thisspecification have been labeled as modules, in order to moreparticularly emphasize their implementation independence. For example, amodule may be implemented as a hardware circuit including custom VLSIcircuits or gate arrays, off-the-shelf semiconductors such as logicchips, transistors, or other discrete components. A module may also beimplemented in programmable hardware devices such as field programmablegate arrays, programmable array logic, programmable logic devices or thelike. Modules may also be implemented in software for execution byvarious types of processors. An identified module of executable codemay, for instance, include one or more physical or logical blocks ofcomputer instructions, which may, for instance, be organized as anobject, procedure, or function. Nevertheless, the executables of anidentified module need not be physically located together, but mayinclude disparate instructions stored in different locations which, whenjoined logically together, comprise the module and achieve the statedpurpose for the module.

Indeed, a module of executable code may be a single instruction, or manyinstructions, and may even be distributed over several different codesegments, among different programs, and across several memory devices.Similarly, operational data may be identified and illustrated hereinwithin modules, and may be embodied in any suitable form and organizedwithin any suitable type of data structure. The operational data may becollected as a single data set, or may be distributed over differentlocations including over different storage devices, and may exist, atleast partially, merely as electronic signals on a system or network.

As shown in FIG. 2, after selecting a targeted information 210 from awebpage 200, a user presses a hot key (for example, by right-clickingthe mouse or pressing any specific key) or uses any other mechanism topop up a pull-down menu 220, and then selects the “Share With” option,such that the browser calls the dispatching engine of the informationcenter server 110. Afterward, the dispatching engine analyzes thecontent of the targeted information 210 according to a “pre-analyzeduser behavior”, and then a window 300 pops up for the user to select anoption therefrom. Afterward, the dispatching engine dispatches theinformation to appropriate candidates by means of candidates' preferencetools. The dispatching engine is described hereunder in detail by makingreference to FIG. 6 and FIGS. 7A through 7C. The “pre-analyzed userbehavior” is described hereunder in detail together with the analyzingengine by making reference to FIG. 4 and FIGS. 5A through 5B.

FIG. 3 shows a screen display demo of a client-end pop-up window 300provided by the dispatching engine according to an embodiment of thepresent invention. The pop-up window 300 includes a message displayingregion 370 and a presenting region 380. The purpose of the messagedisplaying region 370 is to allow the user to select the targetedinformation 210 therefrom. The purpose of the presenting region 380 isto allow all the candidates to be determined according to the analysisof a “pre-analyzed user behavior”. The presenting region 380 has a list320 of all the candidates. Preferably, shown beside each of thecandidates is a photo taken thereof to enable instant identification ofthe corresponding candidate. The candidates in the list can becategorized according to a similarity score. The scores are shown atvertical bars positioned to the left of the photos to indicate aninteresting level of each of the candidates toward the information 210.Candidates with the same interesting level (that is, the same similarityscore) are sorted by name. This technical feature is optional in thepresent invention. Further, it can be replaced by an alternative inother embodiments. As disclosed in the present invention, the candidatescan be screened and selected according to a similarity score threshold.There is a check box 310 to the left of the vertical bar for each of thecandidates. The check box 310 allows the user to select a candidate whomthe information 210 will be dispatched to. According to the presentinvention, the pop-up window 300 can also have a “More Interests . . . ”button 360 whereby the user selects more candidates manually.

The right side of the presenting region 380 has a preference tool zone330 for presenting the tool icons of candidates' preference tool, thatis, providing the tool icons, such as LOTUS SAMETIME 341, MSN 342,FIREFOX 343, LOTUS NOTES 351, or OUTLOOK EXPRESS 352, of one or morepreference tools of each of the candidates for the user to choose from.The tools are sorted by preference level. For example, the tools aresorted by the frequency at which the user uses a tool when interactingwith candidates, such that priority is given to frequently-used tools.In another embodiment, candidates' preference tools at the time ofdispatching the information 210 are further determined by analyzing theaccumulating time that the user spends interacting with candidates bythe tools.

According to an embodiment of the present invention, it is feasible tolist those tools which are active and available to candidates such thatthe user can choose the listed tools, and/or it is feasible to presentenlarged icons of the tools which are available and recommended, and theaforesaid technical features are not restrictive of the presentinvention. The user can manually select a preference tool icon of eachof the candidates; meanwhile, the selected tool icons can be enlargedand displayed, and the aforesaid technical features are not restrictiveof the present invention and thus can be implemented in another mannerin other embodiments.

After determining the candidates and the preference tools of each of thecandidates, the user sends an action message by pressing a “Send” button362, so as to instruct that the targeted information 210 should bedispatched to the selected candidates by candidates' preference tools. Apoint to note is that the aforesaid disclosure that the targetedinformation 210 is selected from the webpage 200 serves an illustrativepurpose only, because, in fact, the targeted information 210 is not onlyselected from a webpage accessed by a browser, but can also be selectedby means of any application capable of text-based interaction. Forexample, the present invention also applies to the scenario where amessage from a friend is received by an e-mail application such as LOTUSNOTES and to be shared via embodiments of the present invention.

FIG. 4 is a schematic view of transmission of messages by the analyzingengine in operation according to an embodiment of the present invention.An information center 400 and an information plug-in (450, 452, 454,456) of each application are two essential elements of the embodiment.The information plug-ins 450, 452, 454, 456 are built in theapplications 440, 442, 444, 446 of the client-end computer(s),respectively, to interact with the information center 400 and therebyshare information. The applications or tools are either installed ondifferent client-end computers, respectively, or installed on the sameclient-end computer, as shown in the drawing, and can be implemented byLOTUS NOTES 440, SAMETIME 442, MSN 444, or INTERNET EXPLORER 446.

As described above, the information center 400 includes an analyzingengine 410, a dispatching engine 420, and a synchronizing engine 430.The information center 400 can be installed on a standalone server tomeet a requirement set forth by a system designer (as shown in FIG. 1),or is executed on each of the client-end computers in a way like anapplication is. In one embodiment, the analyzing engine 410 isimplemented in the form of a daemon, but such a technical feature can bereplaced by an alternative in other embodiments.

In the situation where the users of the client-end computers interactwith friends by preference tools, such as an instant message, an e-mail,or a short message, the information plug-ins 450, 452, 454, 456automatically collect data related to the user behavior and send theuser behavior-related data to the analyzing engine 410 of theinformation center for analysis. According to an embodiment of thepresent invention, user behavior includes the following data (which arenot limited to):

-   -   a. candidates: people interacting with the user;    -   b. delivery type: the employed delivery tools, such as an        instant message system, an e-mail system, a short message        system, or any other system;    -   c. delivery time: the time at which the user sends information;    -   d. source content: information content of interaction between        the user and a friend thereof, such as a message, a mail, a        short message, or any other information expressed in text;    -   e. other alternative information: a description of a location        where the user interacts with a person, the person's gender and        age, and a best available tool of delivery.

User behavior is packaged in the form of a “user behavior message” fordelivery. As shown in the drawings, once the user interacts with afriend thereof by applications A, B, C, user behavior messages 460, 462,464 will be constructed and sent to the analyzing engine 410 foranalysis. The result of the analysis is stored in a user behaviordatabase 470. For example, the information plug-in 450 of LOTUS NOTES440 (application A) retrieves whatever is required for interaction withthe user, such as the mail content, candidates, delivery type(interacting by NOTES), delivery time, or other alternative information,to construct the user behavior message 460. Then, the informationplug-in sends the user behavior message 460 to the analyzing engine 410of the information center for analysis.

The analyzing engine 410 collects all the user behavior messages andanalyzes the collected user behavior messages to retrieve a candidatename, a delivery type, a delivery time, and any other alternativeinformation and analyze source content in order to determine thosecandidates who are interested in the source content. The analysis result466 is stored in the user behavior database 470 to create the“pre-analyzed user behavior”. The analyzing engine 410 is preferablyimplemented in the form of a daemon for analyzing user behaviorautomatically in advance. Please refer to FIGS. 5A through 5B for adetailed description as to how to analyze the source content.

FIGS. 5A and 5B are flowcharts of operation of the analyzing engine 410for creating the “pre-analyzed user behavior” according to a specificembodiment of the present invention. As shown in the drawings, theoperation of the analyzing engine 410 includes the steps of: receiving auser behavior message of an information plug-in from each application(step 510); segmenting source content (that is, information content) ineach of the user behavior messages (step 520); analyzing the informationcontent to determine which group the information content should belongto, so as to determine information and tools preferred by a personinteracting with the user (step 540). The analysis results, togetherwith a candidate name, a delivery type, a delivery time, and any otheralternative information, are stored in the user behavior database 470.

FIG. 5B further illustrates how the analyzing engine 410 analyzesinformation content of the user behavior message. The analyzing engine410 analyzes information content by a conventional information retrievaltechnique. In a specific embodiment of the present invention, theanalyzing engine 410 essentially performs two steps, namely active textclustering 570 and secondary text clustering 580 (described below), toanalyze the information content. The active text clustering 570, whichis based on a conventional grouping technique, involves performing agrouping (that is, categorization) operation on the information contentof all the received user behavior messages. First, the active textclustering 570 has calculating a similarity score between each groupstored in the user behavior database 470 and the information content ofthe user behavior messages according to segmentation result (step 572).

The similarity score is a cosine similarity score between each existinggroup and each information content, and is calculated by a conventionalweighting technique on a term-basis, such as TF/IDF (termfrequency-inverse document frequency), or an equivalent technique.

The TF/IDF weighting technique is usually applicable to vector spacemodel and a cosine similarity score for determining the similaritybetween two documents. In a specific embodiment of the presentinvention, each information content is regarded as a document, and eachinformation content can be expressed as a “vector” according to thevector space model in the aforesaid grouping technique. The vector has acomponent that corresponds to each term in a default dictionary andcarries a weight. Normally, the weight is for assessing how important aterm is to an information content (or a document), by using theaforesaid conventional TF/IDF weighting technique. In general, if a termin the dictionary is absent from the information content, the weightwill equal zero. If a term in the dictionary is present in theinformation content and is of a high count, the weight will be high.Hence, the “vector” represents the information content. A group includesone or more information contents and thus can also be expressed as a“vector”. Hence, a group information usually includes a “group ID” and a“vector” that represents the group. As a result, a cosine similarityscore between vector(X) that represents the information content andvector(Y) that represents the group is defined by equation (1):

$\begin{matrix}{{\cos\left( {X,Y} \right)} = \frac{X\mspace{14mu}\bullet\mspace{14mu} Y}{{X} \cdot {Y}}} & (1)\end{matrix}$

Referring to FIG. 5B, step 574 involves comparing a similarity scorethreshold with a similarity score between each group and the informationcontent to determine one or more shortlisted groups which theinformation content belongs to. Hence, in a specific embodiment of thepresent invention, the active text clustering 570 entails determiningthe similarity between the information content and an existing group“automatically”. During the grouping (or categorization) operationperformed on the information content, if it is detected that no group ispresent, then a group will be created for the information content.Afterward, one or more “vectors” represents one or more shortlistedgroups adding the information content are obtained using a TF/IDFweighting technique, and then one or more group information which hasconsidered the information content (each group information includes a“group ID” and a “vector” that represents the group) of the one or moreshortlisted groups and the user behavior messages related thereto (suchas a candidate name, a delivery type, a delivery time, and any otheralternative information) are stored in the user behavior database 470.

In a specific embodiment of the present invention, prior to the analysisof information content of the user behavior messages, the informationcontent can also be categorized according to a user-made rule (step530), that is, creating a criterion for determining whether theinformation content matches the user-made rule, for example, making arule according to the user's preference, wherein the rule sets forth oneor more terms or a combination thereof for functioning as keywords. Ifthe keywords set forth in the rule are present in the informationcontent, the information content will be attributed to a specific group.There can be one or more user-made rules. For example, the user can maketwo rules as follows:

-   -   Rule 1 sets forth two keyword groups as follows:        -   keyword group 1: IPHONE, 3G, CHUNGHWA        -   keyword group 2: HTC, TOUCH, 3G    -   Rule 2 sets forth one keyword group as follows:        -   keyword group 1: WEB SPHERE, MQ, CHANNEL, EXIT

All the keywords in the same keyword group must be discovered in aninformation content, otherwise the match will fail. This means that allthe keywords in the same keyword group have a logical “AND”relationship. By contrast, the keywords in different keyword groups havea logical “OR” relationship. Hence, once an information content A isobtained, the analyzing engine 410 will check and determine whether theinformation content A has “IPHONE”, “3G”, and “CHUNGHWA”, or “HTC”,“TOUCH”, and “3G”; in response to an affirmative determination, theinformation content A is deemed a group governed by Rule 1. Theanalyzing engine 410 also checks and determines whether the informationcontent A has “WEBSPHERE”, “MQ”, “CHANNEL”, and “EXIT”; in response toan affirmative determination, the information content A is deemed agroup governed by Rule 2. Once the information content A matches one ofthe rules, the other rules need not be checked.

Referring to FIG. 5B, the analyzing engine 410 performs the secondarytext clustering 580 on the information content. First, the analyzingengine 410 acquires the one or more group IDs of the one or moreshortlisted groups obtained from the active text clustering 570 (step582). The groups include the content information. Then, the secondarytext clustering 580 re-obtains one or more “vectors” for representingthe one or more shortlisted groups adding the information content bycombining old one or more “vectors” representing one or more shortlistedgroups previously stored by the secondary text clustering 580 but beingindicated by the one or more group IDs with the information content, byusing the TF/IDF weighting technique (step 584).

That is, the step is to re-calculate the one or more “vectors”representing one or more shortlisted groups previously stored by thesecondary text clustering 580 by combining the old one or more “vectors”in conjunction with the information content. The old one or more“vectors” do not consider the information content. Afterward,re-obtained one or more group information (each including a “group ID”and a “vector” representing the group, as described above) of the one ormore shortlisted groups and the user behavior messages related thereto(such as a candidate name, a delivery type, a delivery time, and otheralternative information) are stored in the user behavior database 470.In addition, the one or more group information (each including a “groupID” and a “vector” representing the group in conjunction with theinformation content) of the one or more shortlisted groups obtained fromthe active text clustering 570 and the user behavior messages relatedthereto are not necessarily stored in the user behavior database 470.

The one or more group information of the one or more shortlisted groupsobtained from the secondary text clustering 580 and the user behaviormessages related thereto can replace directly those from and related tothe active text clustering 570. A point to note is that, in the stage ofcreating the “pre-analyzed user behavior” solely by the analyzing engine410, the active text clustering 570 yields the same result as thesecondary text clustering 580 does. In a dispatching stage describedbelow, it is possible for the user to select a group directly andmanually in step 728 (described below) and adjust manually the selectedgroup, and thus the one or more shortlisted groups are not exactly thesame as what is obtained automatically by the active text clustering570. As a result, one or more “vectors” which are directly re-calculatedto represent the one or more shortlisted groups that contain theinformation content are not exactly the same as the result obtained bythe active text clustering 570 (step 584). It is because there is onlyone source inputted into the active text clustering 570, while there aretwo sources inputted into the secondary text clustering 580.

FIG. 6 is a schematic view of transmission of messages by thedispatching engine 420 in operation according to a specific embodimentof the present invention. As shown in FIG. 2, after selecting a targetedinformation 210 from a webpage 200, a user presses a hot key or uses anyother mechanism to pop up a pull-down menu 220, and then selects the“Share With” option, and in consequence the information plug-in 456 ofthe browser 446 sends a “share request message 490” to the dispatchingengine 420. The share request message 490 at least has targetedinformation and the current time. After receiving the share requestmessage 490, the dispatching engine 420 analyzes the content of thetargeted information 210 according to a “pre-analyzed user behavior”,presents a candidate list and candidates' preference toolsautomatically, and sends action messages 480, 482, 484 to theinformation plug-ins 450, 452, 454, respectively, so as to dispatch theinformation to appropriate candidates by the candidates' preferencetools. The action messages 480, 482, 484 at least include the targetedinformation and candidate names. The dispatching engine 420 is describedin detail below by reference to FIGS. 7A through 7C.

FIGS. 7A, 7B, and 7C are flowcharts of operation of the dispatchingengine 420 according to a specific embodiment of the present invention.First, as shown in FIG. 2 before, a targeted information 210 isselected, and the dispatching engine 420 receives a share requestmessage sent from an information plug-in of an application (step 710).The dispatching engine 420 calls the analyzing engine 410 in order toanalyze the targeted information content included in the share requestmessage (step 720). Step 720 is described in detail below by referenceto FIG. 7B. In step 730, the dispatching engine 420 presents a list ofpotential candidates and related preference tools (that is, applicationsfor sending information, as described above). Furthermore, as shown inFIG. 3, the user can manually select more candidates by means of the“More Interests . . . ” button 360 (steps 740, 770). Otherwise, thedispatching engine 420 will determine the tools for sending a targetedinformation (step 750). Step 750 is described in detail below byreference to FIG. 7C. Afterward, the dispatching engine 420 sends the“action messages” to the corresponding information plug-ins of theapplications of selected candidates, respectively (step 760).

FIG. 7B illustrates the step 720 in detail. Likewise, step 721 involvessegmenting the content of the information to be shared. Afterward, ifthe user-made rule is available, compare and determine whether thetargeted information matches the user-made rule (step 722). In responseto a negative determination, call the analyzing engine 410 to calculatea similarity score between the targeted information content and eachgroup acquired by the secondary text clustering 580 and stored in theuser behavior database 470 (step 723). Then, step 724 involves comparingthe similarity score with a similarity score threshold to determine oneor more shortlisted groups which the information content belongs to.Step 725 involves storing the similarity score and related candidatedata. If it is determined that there is no further group for thecalculation a similarity score between the targeted information contentand the group (Step 726), then it further needs to determine if there isany shortlisted group available (Step 727). If it is determined thatshortlisted groups are absent, then the user has to select a group and acandidate directly and manually (step 728), otherwise it is necessary tooutput the similarity score and related candidate data directly (step729). The similarity score is for creating the vertical bars lying tothe left of the photos shown in FIG. 3, so as to indicate thecandidates' interesting level in the information 210. After one or moregroups and candidates directly selected by the user, the analyzingengine 410 shown in FIG. 5B is called to perform the secondary textclustering (Step 580) to the targeted information, so as to re-calculateone or more “vectors” for representing the shortlisted groups containingthe targeted information content. In other words, the shortlisted groupsare manually adjusted.

FIG. 7C illustrates how to determine the tools for sending a targetedinformation. First, the dispatching engine 420 obtains all thepreference tools of a candidate (step 751), and sends a candidate nameto the information plug-in of each application (or tool) to confirm itsavailability in the application (step 753). Determine whether anavailable tool is present (step 755) and, in response to an affirmativedetermination, enter it to an available list (step 757). Finally, thedispatching engine 420 categorizes the available list according topreference level (step 759) and creates the preference tool zone 330 forpresenting the tool icons of candidates' preference tools as shown inFIG. 3.

In one embodiment of the present invention, in step 723 the dispatchingengine 420 accesses an open user behavior database 472 or other userbehavior database 474 at a remote end; hence, the engine is not onlyaware of local user behavior, but is aware of all the other open userbehavior. Accordingly, the present invention is applicable toinformation sharing to a greater extent, such as a project that requirescoordinated cooperation or sharing information within a largetransnational company.

FIG. 8 is a flowchart of operation of the synchronizing engine accordingto an embodiment of the present invention. There will be a need forsynchronization between user behavior databases of the differentclient-end computers, respectively, provided that each of the client-endcomputers includes a user behavior database and an information centerbuilt in the information center server 110, and each of the applications(such as an instant message system, an e-mail system, or a short messagesystem) has an information plug-in. Once a client-end computer isconnected to another client-end computer, the synchronizing engine ofthe client-end computers will be signaled to start the synchronization(step 810). Afterward, if the synchronization between the databases isrequired, the synchronizing engine will perform the synchronizationbetween user behavior and action messages on available applications (ortools) (steps 820, 830). Due to the synchronization of unfinished actionmessages, the user can still dispatch information at appropriate times.

In general, the synchronizing engine also determines how to coordinateuser behavior databases. For example, if a client-end computer is amobile device and is capable of sending information only by means of ashort message, the synchronizing engine can only synchronize datarelated to a short message so as to minimize the required storage spaceof the device. To share knowledge, the synchronizing engine synchronizeslocal user behavior and remote open user behavior databases. As aresult, although the user does not have good experience in a certaintheme, the user can still share information with an appropriate personby making use of another person's experience when confronted with theneed to dispatch information; and this advantage is particularlyvaluable when it comes to a business that relies upon coordinatedcollaboration of teams.

FIG. 9 is a schematic view of transmission of messages by thesynchronizing engine 906 operating and having a standalone informationcenter server according to an embodiment of the present invention. Dueto the presence of a standalone information center server, there is notany need for synchronization of user behavior databases. However, if anunfinished action message is present in a client-end computer connectedto the information center server, the synchronizing engine 906 can allowthe user to dispatch information at appropriate time.
